Abstract

An optical short pulse reshaping device capable of effectively eliminating noise from or reshaping of input optical short pulses of a pulse width of pico-second order shorter than a carrier life time. The device comprises: a semiconductor laser element (11;17); means (12) for injecting an electric current to the semiconductor laser element for obtaining an oscillation state of the semiconductor laser element; means (13;14;18) for injecting into the semiconductor laser element input optical short pulses of a wavelength shorter than that of the oscillation light of said semiconductor laser element, and means (16;19) for taking out optical short pulses emitted from the semiconductor laser element distinct from its oscillation output light.
